Application July 23, 1947, Serial No. 762,906

3 Claims. 1

The present invention is directed to a nonslip boot attachment which in practice may be detachably secured to the heel of a boot and is provided with means for separation in placing it on a boot heel, with means for guiding the parts of the boot attachment in the separation thereof and for locking the structure in its heel attachment position. y

Another feature of the invention is that projections or caulks are provided which will penetrate the ground and prevent slipping when the wearer, for example, is walking on soft ground or ground covered with water, as in fishing. And in one modification of the invention, said caulks may also be provided in a form to prevent slipping'on such ground; or in the winter, prevent slipping on ice.

An understanding of the invention may be had from the following description, taken in connection with the accompanying drawing, in which,

Fig. 1 is a perspective view of the non-slip boot attachment of my invention,

Fig. 2 is a plan view thereof,

Fig. 3 is an under plan view showing the structure separated for application to a boot heel,

, Fig. 4 is a side elevation,

Fig. 5 is an and elevation,

Fig. 6 is a transverse vertical section between the open and closed ends of the structure, and

Fig. 7 is a fragmentary vertical section through the double purpose caulk structure which may be used.

Like reference characters refer to like parts in the several figures of the drawing.

The boot heel attachment is made of two parts, each with a horizontal bottom member I and with an upwardly extending flange 2, which when the two parts are together provide a horizontal bottom upon which the lower side of a boot heel may rest, and the flanges 2 embrace the sides and continue around the back of the heel. Caulks in the form of projections 3 extend downwardly from the parts I of the structure and are designed to penetrate the earth in walking thereon. When, as may be desirable attimes, walking on ice is to be done, the caulks 3 may consist of a body, as shown in Fig. 7, interiorly bored and threaded from its upper end downwardly for a distance, adapted to be detachably screw connected with a projection 4 from a bottom member I, which is exteriorly threaded and pointed at its lower end. Removing the body 3 will leave the pointed or sharpened caulk 4 which will penetrate the ice and prevent slipping.

From the sides 2, tapered sharpened horizontal pins 5 extend inwardly toward each other to penetrate opposite sides of the heel to which attached. In general the device will be used with boots which are used in fishing, therefore of a rubber character with rubber heels. The two parts are separated at their division line as shown in Fig. 3 in placing the device upon a heel, and are then forced toward each other to drive the pins in the opposite sides of the heel.

At the under side of one of the bottom sections I, at its front and toward the rear, two fiat strips of spring material 6 and l are laid one over another and connected at one end by a screw 8. They ride in grooves 9 at their free end portions in the bottom section i of the other half of the device, so that when the two halves are separated, they are properly guided with respect to each other. Between their ends the strips 6 and l are pressed upwardly in humps III, which when the two halves of the device are together, seat in notches or recesses made in the associated bottom section I to receive them.

After the non-slip device has been put upon a heel, the two halves thereof, having been separated as in Fig. 3 and then forced together to drive the pins 5 into opposite sides of the heel, are releasably locked against separation. At the under side of each of the bottom sections l, they are thickened between the ends of the device, as at H, to provide a sufficient body that a horizontal opening may be made therethrough for passage of a rod [2 (Fig. 6). At one end it is equipped with a nut l3, which may be screw operated for adjustment. It seats in a suitable recess provided for it. At the other end it is equipped with a head [4 which has a groove around it between its ends. A coiled compression spring I5 is located around the rod l2 in an opening to receive it, bearing at one end against the bottom of the opening and at the other against the inner end of the head I4. When the two halves of the device are separated, th spring is compressed and the head l4 moves into the opening Hi.

When the two halves are together, the head I4 is in a position to be engaged by a slidable latch I! mounted vertically in a side 2 as shown in Figs. 1 and 6, in a recess [8 provided therefor. The lower end of the latch I! has a slot with spaced legs, one at each side of the slot, the legs enter the groove and embrace the smaller annular portion of the head M, at the groove as shown. The latch slidably held in place by a retaining flat bar [9, which permits slidable movement but not disconnection.

The structure described is readily and economically produced and serves the purposes for which it has been designed in a very efiective manner. The device attached to the heel of a boot is firmly held against disconnection by the penetrating pins 5, and by the described lock which prevents separation of the parts and a disconnection from a boot heel until the latch l! is moved upwardly to disengaged position.

The invention is defined in the appended claims and is to be considered comprehensive of all forms of structure coming within their scope.

I claim:

1. In a structure as described, two heel members each having a bottom section and an upstanding rib around the edges thereof, said members being adapted to be placed together at -the free edges of said bottom sections, caulks extending downwardly from each bottom section, means connecting said members together for movement toward or away from each other, means attached to one of said members and operatively associated with the other for guiding th m in their movements, means for releasably locking said members together in closed position, said means releasably connecting said parts together comprising, a rod extending transversely of and through the bottom sections thereof, said rod having a head at both ends, and the bottom section of one of said members having an opening through which the rod passes of a larger diameter than the diameter of the rod, and a coiled spring around the rod between the bottom of said opening and the inner end of its associated head.

'2. In a structure as described, two heel members each having a bottom section and an upstanding rib around the edges thereof, said members being adapted to be placed together at the free edges of said bottom sections, caulks extending downwardly from each bottom section, means connecting said members together for movement toward or away from each other, means attached to one of said members and operatively associated with the other for guiding them in their movement, means for releasably locking said members together in closed position, said means releasably connecting said parts together comprising, a rod extending transversely of and through the bottom sections thereof, said rod having a head at both ends, and the bottom section of one of said members having an opening through which the rod passes of a larger diameter than the diameter of the rod, a coiled spring around the rod between the bottom of said opening and the inner end of its associated head, said head against which the spring bears lat one end having an annular groove around it between its ends, and a latch member slidably mounted on an adjacent upwardly extending rib of one of said members having a slotted lower end and movable at each side of said slot into and out of said groove.-

3. A non-slip .boot attachment comprising, a heel member in two halves, each having a bottom section and an upwardly extending flange, said bottom sections at adjacent free edges being adapted to be brought together, means connecting said halves for relative movement toward and away from each other and for limiting the extent of separation thereof, guide strips secured at the under side of the bottom sections of one of said halves and extending to and over the bottom section of the other of said halves, said bottom section of the other of said halves having a guide groove therein for said strips, said strips between their'ends having an upwardly extending projecting portion beyond the bottom section to which the strips are attached, and the other of said bottom sections having recesses to receive them when the two sections are together, .said strips being of spring metal material.
